"content": "A reminder that energy storage doesn't have to be dependent on batteries.\n\nThe Welsh 'Electric Mountain' facility is a pumped-storage mechanism utilising the force of gravity to store energy.\n\nWhen electricity is cheap you pump it up the hill, when surge use is required, you let it flow back down through the turbines. \n\nExpensive infrastructure to set up, but cheap to run, with a long working life. The beauty of civil engineering exemplified!\n\n#energy #storage #climate \n\nhttps://www.theguardian.com/news/2023/nov/02/beauty-of-infrastructure-electric-mountain-dinorwig-power-station-north-wales",
